To all whom it may concern."

Be it known that l, EDWARD J. FLYNN, Jr, a citizen of the United States, residing at WVoodlawn, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Treating Steel Ingots, of which the following is a specification.

This invention relates to improvements in apparatus, commonly known as soaking-pits, for treating steel ingots.

The primary object of this invention is to provide an apparatus for the purpose set forth, so constructed as to insure an equal distribution of the heat around the ingots, thereby equalizing the temperature thereof.

Another important object of this invention is to provide an apparatus for the purpose set forth, that will facilitate the cleaning of the pit.

Still further objects of this invention are 7 to provide an apparatus for the purpose set its forth, which is comparatively simple in its construction and arrangement, strong, durable and efiicient in its use and inexpensive to manufacture.

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts, specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention.

In the drawings, forming a part of this specification in which the same reference characters designate corresponding parts throughout the several views: Figure 1 is a vertical sectional view of a soaking-pit, embodying the improvements in accordance with this invention. Fig. 2 is a top plan view thereof with a portion of the soakingpit broken away. Fig. 3 is a longitudinal cross sectional view of a soaking-pit embodying this invention. Fig. 1 is a vertical sectional View of a modification of the intermediate stationary portion of the bottom of the pit.

The improvements in soaking-pits em bodied in this invention consists principally in the improved construction of the bottom and in the sides of the said pit.

Referring more in detail to the drawings, 1 designates the pit, showing the ingots 2 p'laced therein. The stationary bottom portion 3, of the pit 1, is constructed to form an intermediate elevated portion inclining specification of Letters Eatent.

able refractory material.

Hingedly connected, as illustrated at 8, to the lower end of the inclining portions 4 of the stationary intermediate portion 3, are

the bottom portions 7, likewise covered with suitable refractory material 10 and adapted to swing downwardly in the cellar 9, as shown in dotted lines, Fig. 1.

It will be readily apparent from the foregoing description that the intermediate stationary portion 3, increasing gradually in height rom each end to its center, taken in connection with the hinged bottom portions 7, will greatly facilitate the cleaning of the pit, as all refuse may be readily removed from the inclining surfaces 4 and dropped through openings in bottom when hinged bottom portions 7 are swung downwardly.

As shown at 11, the inside surfaces of the side walls 12 of the pit 1, are so constructed as to project inwardly so that when the ingots 2 are placed within the said pit there will be but two lines of contact, namely, the

. side 13 of the ingots 2 against the inward projection 11, and the lower edge 14 of the ingots 2 on the inclining surface 1 of the elevated stationary bottom portion 3, said contacts maintaining the sa1d ingots in an upright position, thereby assuring an equal distribution of the heat around the ingots.

Owing to the pressure of the ingots 2 against the side walls 12, of the pit 1, said side walls may be reinforced with structural steel, as shown at 15, Fig. 1.

For the psurpose of closing and opening the hinged ottom portions 7 any operable mechanical device may be employed.

As illustrated in the modification in Fig. 4, the intermediate elevated portion 3, can also be constructed to form a curved elevation instead of running to a point as shown in Fig. 1.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while describing the principle of operation of the invention together with the apparatus which is i now considered to be the best embodiment thereof, it isto be understood that theap- V paratus shown is merely illustrative and that various changes in the form, proportions and the minor details of construction may be resorted to without departing fromthe principle or sacrificing any of the advantages of the invention as defined in the appended claims.

What I claim as new and desire to secure by Letters Patent is: I

I. An apparatus for the purpose set forth comprising a soaking pit having its bottom provided with u wardly extending supporting portions an each side wall wlth an inwardly extending abutment, said supportmediate ing portions adapted to contact with the inner corners of a air of opposed ingots and each abutment a apted to contact with the outer side of each ingot of said opposed ingots for maintaining these latter in an upright position at each side of the center of the p1t and spaced from each other and spaced from said sides and bottom to obtain an equal distribution of heat around the ingots.

2. An apparatus for the purpose set forth pit'having the inter comprising a soaking ortion of its ottom gradually increasing 111 height from each end toward the center to provide a pair of ingot supports to the lower ends of which are hingedly at tached downwardly swinging dumping portions, said pit further having each side wall provided with an inwardly extending abutment, said ingot supports adapted to contact with the inner corners of a pair of opposed ingots for maintaining these latter in an upright position and spaced from each other and further spaced from said sides and bottom to obtain anequal distribution of heat around said ingots.

3. An apparatus mediate portion of its ottom gradually increasing m height from each end toward the for the purpose set forth comprising a soaking it having the intercenter to provide a pair of supports, said pit further havlng each side wall provided gots.

In testimon whereofI aflix my signature in presence 0 two witnesses.
